There are different possible uses of bauxite residue in construction, for instance in cement production (clinkers, composite cements, and alkali-activated cements), as raw material and additive in iron and steel production, as a pigment in concrete and brick, as road base, as embankment and backfill material, also capping of landfill sites and for soil improvement [6, 23].

The lime is added as a fluxing agent during steel production. Lime can absorb water through hydration for many years after the slag has been created. This hydration process can produce volume expansions of 10 percent or more. Moisture absorption and slag expansion can occur even for slag fills located above the water table and beneath buildings.

Introduction to Backfill in Construction. In construction, backfill refers to the material used to fill a trench or hole after the installation of underground utilities, foundations, or other construction elements. Backfilling is a critical step in construction projects, as it ensures the stability, safety, and longevity of the structure.

Wood waste from the construction industry (WCW) is a biomass source with economic value applications and can be used in the market as fuel. One of the bottlenecks of implementing WCW in urban centers is the continuous availability of materials to meet the demand, which is allied with the WCW contaminations and promotes high ash content.
